Abstract
The invention relates to a fixture for a concave ring forging of a tire mold, which comprises an upper punch, a lower punch and a core roller, wherein the upper punch is formed by coaxially arranging a reverse truncated cone segment and a cylinder segment in sequence from top to bottom as a whole, and the minor diameter of the reverse truncated cone segment is equal to the diameter of the cylinder segment; the lower punch is a truncated cone; the diameter of the cylinder segment of the upper punch is not smaller than the minor diameter of the truncated cone of the lower punch; and the core roller is formed by coaxially arranging an upper cylinder segment, a middle cylinder segment and a lower cylinder segment in sequence from top to bottom as a whole. The fixture is suitable for forging the concave ring forging of the tire mold, and the concave ring forging can be smoothly rolled and completely filled.
Description
Technical field
The present invention relates to tire-mold concave shaped ring forgeable piece tool.Be mainly used in the forging of automobile tire mould concave shaped ring rolling spare, belong to the forging special-shape ring technical field of mold.
Background technology
The application at home and abroad of tire-mold concave shaped ring rolling spare is very extensive, especially aspect the doughnut moulding wide prospect is being arranged, and is the important shaped device of producing doughnut.The structure of tire-mold concave shaped ring rolling spare is as shown in Figure 5, is provided with annular concave step 51 in the centre bore hole wall of ring rolling spare 5.The processing method of tire-mold concave shaped ring rolling spare is at present: adopt machined, the material that machines away inner ring central concave position is to obtain concave step.This kind processing method is processed complex not only, and the waste of raw materials phenomenon is serious, and production cost is higher.
Summary of the invention
Technical problem to be solved by this invention is: a kind of frock that can process tire-mold concave shaped ring rolling spare simply is provided, and can reduces raw-material wasting phenomenon, thereby reduce production costs.
For addressing the above problem; The technical scheme that the present invention adopts is: tire-mold concave shaped ring forgeable piece tool; Comprise upper punch, low punch and core roller; Described upper punch constitutes an integral body by falling frustoconical section with coaxial setting of shell portion from top to bottom successively, and the minor diameter of frustoconical section equals the diameter of shell portion; Described low punch is a truncated cone; The diameter of the shell portion of upper punch is not less than the minor diameter of the truncated cone of low punch; Described core roller constitutes an integral body by coaxial setting of last shell portion, mediate cylindrical section and following shell portion from top to bottom successively, and the diameter of wherein going up shell portion is less than the mediate cylindrical section diameter, and the mediate cylindrical section diameter is greater than following shell portion diameter.
The diameter of the shell portion of described upper punch equals the minor diameter of the truncated cone of low punch.
The diameter of the last shell portion of described core roller equals the diameter of shell portion down.
The last shell portion and the transition position between the mediate cylindrical section of described core roller are fillet; Transition position between described mediate cylindrical section and the following shell portion is a fillet.
The invention has the beneficial effects as follows: above-mentioned tire-mold concave shaped ring forgeable piece tool, simple in structure, easy to use.Adopt above-mentioned tire-mold concave shaped ring forgeable piece tool, can process tire-mold concave shaped ring rolling spare simply, and can reduce raw-material wasting phenomenon, thereby reduce production costs.

The specific embodiment
Through specific embodiment tire-mold concave shaped ring forgeable piece tool of the present invention is done further to describe in detail below.
Tire-mold concave shaped ring forgeable piece tool; Comprise upper punch 1, low punch 2 and core roller 3; The structure of described upper punch 1 is as shown in Figure 1; Constitute an integral body by falling frustoconical section 11 with shell portion 12 coaxial settings successively from top to bottom, the minor diameter of frustoconical section 11 of falling equals the diameter of shell portion 12; The structure of described low punch 2 is as shown in Figure 2, is truncated cone; The diameter of the shell portion 12 of upper punch 1 is not less than the minor diameter of the truncated cone of low punch 2, and the minor diameter that wherein equals the truncated cone of low punch 2 with the diameter of the shell portion 12 of upper punch 1 is the best; The structure of described core roller 3 is as shown in Figure 3; From top to bottom successively by last shell portion 31, mediate cylindrical section 32, shell portion 33 coaxial settings constitute an integral body down; Wherein go up the diameter of the diameter of shell portion 31 less than mediate cylindrical section 32; The diameter of mediate cylindrical section 32 is greater than the diameter of following shell portion 33; The diameter of the last shell portion 31 of described core roller 3 equals the diameter of shell portion 33 down, and the last shell portion 31 and the transition position between the mediate cylindrical section 32 of described core roller 3 are fillet; Transition position between described mediate cylindrical section 32 and the following shell portion 33 is a fillet.
Operation principle of the present invention is: when stating tire-mold concave shaped ring forgeable piece tool in the use and being rolled; At first adopt low punch 2 the blank material to be gone out the following hole of a cone; Thereby adopt upper punch 1 to go up punching then and make structure blank material 4 as shown in Figure 4; Adopt core roller 3 to stretch in the interstitial hole 41 of blank material 4 at last and roll over ring, roll out the annular concave step 51 of ring rolling spare 5, finally make structure ring rolling spare as shown in Figure 55 through the mediate cylindrical section 32 of core roller 3.Wherein, when adopting core roller 3 to roll over ring, because the middle part of core roller 3 is a mediate cylindrical section 32; So can make rolled piece can be rolling steadily, to fill type complete, and then reduced the scrappage of ring rolling spare 5, practiced thrift material; Save the energy and man-hour, improved operating efficiency.
The invention has the beneficial effects as follows: above-mentioned tire-mold concave shaped ring forgeable piece tool, simple in structure, easy to use.Adopt above-mentioned tire-mold concave shaped ring forgeable piece tool, can process tire-mold concave shaped ring rolling spare simply, and can reduce raw-material wasting phenomenon, thereby reduce production costs.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
